Any and all constructive feedback is great! Thank you.

9/13/2021: revised layout


Finally, a 40% board with ISO! Sign me up!


after some feedbacks, I realize that the 1.5u right shift is too exotic, I know there are a few keysets which include this key, but it is still scarce.
so I decided to change the right shift to 1u + 1.75u or 1.75u + 1u or 2.75u

I hope this could remedy the keycap problem. :smiley:

edit: I will order the new PCB revision soon!
